+    # >>> Defragmenting DNS - Determining the optimal maximum UDP response size for DNS <<<
+    # by Axel Koolhaas, and Tjeerd Slokker (https://indico.dns-oarc.net/event/36/contributions/776/)
+    # in collaboration with NLnet Labs explored DNS using real world data from the
+    # the RIPE Atlas probes and the researchers suggested different values for
+    # IPv4 and IPv6 and in different scenarios. They advise that servers should
+    # be configured to limit DNS messages sent over UDP to a size that will not
+    # trigger fragmentation on typical network links. DNS servers can switch
+    # from UDP to TCP when a DNS response is too big to fit in this limited
+    # buffer size. This value has also been suggested in DNS Flag Day 2020.
